ALSA: usb-audio: Properly match with audio interface class
There are a few entries in the quirk table that set the device ID with USB_DEVICE() macro while having an extra bInterfaceClass field. But bInterfaceClass field is never checked unless the proper match_flags is set, so those may match incorrectly with all interfaces. Introduce another macro to match with the vid/pid pair and the audio class interface, and apply it to such entries, so that they can match properly.
